EG Auto Add to Cart Free Gift

I used this app specifically so that it would add a product and a discount to the cart for a send X get Y Free promotion. The app's description said that it would do this and had the features to do this, but never worked. When I contacted Customer support, I found them to be rude and unhelpful. I deleted the app after 2 days and would never recommend this app unless you're a competitor. of mine.
